IMPEOVED BED-BOTTOM.

@Ligt .tlgehtli referat in it tigen man what aut mating mi at tte stmt.

TO ALL WHOM IT MAY CONGERN Be it knownthatI, JOHN ALLEN, of Pughto'en, in the county of Chester, in the State of Pennsylvania, have invented a-new and useful Improvement in Bed and Seat-Bottoms and do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in whichi i Figure 1 is a plan view of my improved bed orseatfbottcm.

Figure 2 an end or elevation view of the same.

Figure 3 a diagram, showing one of the different ways of applying my invention to bod or seabbottoms.

The nature of my invention consists in the use of strips of metal or any like inelastic material for the construction of bedstead and seat-bottoms, said strips being jointed together in such a way as to combine elasticity, self-adjustableness, and equalization of strain.

To enable others skilled in the art to make and use my invention, I will now proceed to'describe its" con1 struction and operation.

A A is a bed-bottomframe, made of wood or metal, as the case may be.

K K are knobs, secured fast into frame A, at suitable distance from each other.

The bed-bottom, as shown in fig. 1, is composed of twe distinct strip-works, as shown by the two different tints used in the drawings', brown and blue. The strip-work, tinted brown, is composed of main metallic strips a, e, b, c, f, m, 0,1, and 7, connected or jointed together with shorter and centre strips, c, vi, g, h, Z, n, p, q, and 7, by means of rivets or any other means of obtaining articulated joints.

The blue strip-Work is entirely similar to the one above described. l The outer ends of main`strips of both series being provided with rings, or any other contrivances-to hold fast on each of the knobs K K, I set the rst strip-work on to said knobs, as shown in fig. 1, stretching said ,brown strip-work towards both ends of frame A, by means ci' braeing-`strips 1 and 2, riveted or articulated ino The blue strip-work,'entirelysimilar to the brown one, is'intertwined with the latter,`and set 'onto every' other knob in the frame; also stretched towards both ends by means of bracing-strips 3 and 4.

It is obvious that if at any time I want to undo my bed or seat-bottom, Ihave simply to unhook or undo one of the bracing-strips 1 2 or 3 4, and the whole work the undone bracing-strip belongs 'to will be loosened.

The simplicity of this whole arrangement is obvious, and hardly needs any demonstration.

The strips are mad-e eithercf iron hoop, steel, or zinc, 'or thick tin,'wod,' or leather; in a word, of any inelastic metal or material, and can be got at a very triing cost.

` The construction is simple, the whole is leasily set on and loosened, easily stretched, and the series of intertwined articulatdjoints is bound to insure elasticity without unequal strain.

I do not desire te confine myself' to the'dispositipn and combination of the brown'and blue strip-work above described. I also reserve the right to vary the form of the strips, their length; also modify, when desired, the relative dimensions of the main and intermediate strips, vary their number at will; in a -Word, usingany system or combination which will answer my intended purpose, and to have a construction substantially the same, and

'consequently based on the same principle, as the one above described.

I do not intend using my system for bedstead-bottoms only; I do reserve the right to construct any seatbottoms of any kind in the manner above described for bedsteads.

I do not broadly claim having invented the mode ot' making bed or seat-bottoms with inelastic strips or bands, but simply the special construction or mode ofv combining and intertwining them as above explained.

Having thus described my invention, what I claim as rnyrinvention, and desire to secure by Letters ffatent of the United States, .isl The hed-bottom constructed of inelastic bands or strips, joined together in thines, crossing each other in the middle, as shown, being supported by rings upon the. rails of the bedstead, and stretched sidewise by the bands 1 2, 3 4, and 7, the whole constructed in the manner and, for the purpose above set forth and described.l

JOHN ALLEN.
